PLATE GLASS SETTING Nov. 22, 1932. I

Filed Dec; 14, 1929 Patented Nov. 22, 1932 UNITED STATES PATENT orrics CLAES GEORG URBAN KBEfTGER AND SIGURD LEWERENTZ, OF STOGKHQIM, SWEDEN PLATE enass :snrrlnor Application filed December 14, 1929, Serial No. 414,185, and in Sweden December, 1928.

This invention relates to plate-glass settings, such as window sashes, cases or frames, particularly for store front windows, show windows and the like, in which the windowpane or glass plate is yieldingly secured in the frame or sash.

The chief object of the invention is to provide an improved setting of the glass plate in the sash or frame causing the glass plate to fit perfectly tightly therein while avoiding all dangerous strains at the setting and preventing all outer pressure from being passed over to the glass plate. Thus, the risk of breaking the glass otherwise caused thereby is eliminated.

The invention consists, chiefly, in this that the glass plate is held in position in the sash or frame by a detachable non-resilient moulding, which is attached to the sash by means of screws or the like to form a substantially rigid construction and against which the glass is pressed by a securing metal strip placed inside the glass and provided with resilient flanges or tongues. Preferably, the

moulding directly abuts against the sash with an engaging surface, through which the fixing screws pass, so as to permit the moulding to be stoutly bolted to the frame and so as to bring the edge or flange of said moulding,

which holds the glass in position, in a completely fixed, immovable position when attaching said moulding to the frame, so that the glass is not subjected to inca-lculable no strains at the setting. \Vhen the screws are tightened they will consequently press the moulding to abut against thesash ti htly but they cannot in any case bring said moulding in an oblique position and will always only effect a uniform pressure at right angles to the 0 plane of the plate glass said pressure causing a compression of the resilient securing strip provided between the glass and the sash so that said strip is caused to press the glass to against the moulding on the opposite side of the lass.

T e invention is illustrated in the annexed drawing showing some embodiments thereof. Fig. 1 is a perspective view of a part of a corner-window mounted according to the abut tightly and with a uniform pressure ous conditions.v

The embodiment shown in Figs. 1 and 2 is for corner windows. The window frame or sash consists also in this case-of a frame 1 of angle iron while the moulding 4 is substan tially T-shaped in crosssection and the Web ,7 thereofdirectly abuts against the frame 1 and is attached to it by means of fixing screws 6 directly screwed in the web. One flange 14 of the moulding is parallel with one flange of theframe of angle iron said latter flange carrying the metal strip *9 which presses one window-pane 8 against said flange 14 of the moulding by means of its resilient tongues 10. The other flange 15 of said moulding is bent to form the outer support or stop for theothe-r window-pane 8 said last-men- 1 tion-ed pane being pressed to abut tightly against said flange 15 by other tongues 10a on the strip 9. Figs. 3 and 4 illustrate how the angle between the two adjacent panes in the corner may be made acute or obtuse so while no other modification of the embodiment shown in Fig. 2 is necessary than that, which comprises turning the tongues 10a to fit to the new angle. In the embodiment shown in Fig. 5"the window-case consists of a frame '1 of angle iron and a moulding 4 attached to the outer side of the frame. Said moulding has a' substantially rectanguilar hollow cross-section having two adjacent sides 41, 42 cut oil. The side 41 directly engages the out side of the frame 1 and is secured thereto by means of fixing screws 6 while the edge of the side 42 forms a support or holder for the glassS pressed against said edge by a sew curingstrip 9 of essentially the same design as that of the embodiments described above. The moulding is substantially U-shaped in cross-section having onenarrower flange 41 and one broader flange 42. "The plane inner surface of the flange 42 forms a supporting surface for the glass 8 which is pressed against said surface by a securing strip 9 of sheet metal having resilient tongues 10, in the same manner as in the embodiments described above. The embodiment according to Fig. 6 is a modification of that shown in Fig. 5 to adapt the latter to windows having double glasses. The moulding 4 for the outer window-glass 8a is of the same design as that of Fig. 5 while the inner glass 8 is held by a. moulding 17 of Z-shaped cross-section one flange of which engages the inner side of the frame 1 of angle iron and is secured thereto by means of fixing screws .6 while the other flange thereof abuts against the inner glass 8. The se curing strip 9 is provided with resilient tongues or flaps, 10 and 10a pressing'the glasses 8 and 8a against their-mouldings 17 and 4, respectively.

Fig. 7 shows a cross section of a vertical or horizontal window-bar between two glass pl'ates8, 8a lying in the same plane. The frame 1 is here rectangular in cross-section while the molding 4 common to the two glass plates is T-shaped in cross-section. The web of the molding is rigidly screwed to the frame 1 while the two glasses 8, 8a are pressed outtowards the arms or flanges of the molding. by the resilient tongues 10 of a strip 9 carried by the frame 1. The

outer moulding 1 is in Fig. 8 substantially T-shaped in cross-section but has a U-shaped web for double windows. The

7 frame 1 ishere of rectangular cross-section.

The outer glass plates 8a,8a are held by a common moulding 4a corresponding to the moulding of Fig. 7 while the inner glass plates 8, 8 are held in position by a moulding The two mouldings 4, 4a are secured to a rigid construction is formed. The glass plates 8, 8a are pressed against the mould ings by securing strips 9, 9 of sheet metal carrie by the frame 1 and provided with resilient tongues.

In all embodiments described above the resilient means are independent of the mouldings and the latter may, therefore, be made quite rigid and joined with the window frame or sash to a rigid construction, whose shape is quite independent of the fact how much the fixing screws for the moulding are tightened. This fact renders it possible to make the mouldings of the material best fit for the individual case in question and to attain an intermediate space between the frame (or sash) and the moulding exactly dimensioned for the glass plate and its resilientmeans.

The invention is not limited to the embodiments shown in the drawing. For instance, the resilient securing strip may in double windows consist of a resilient strip of sheet metal bent in U-shape and placed between the glass plate without any intermediate carrying part said strip pressing the two glass plates against the moulding by means of its resilient legs. It is obvious that the invention is applicable to all kinds of easements, sashes, cases or frames, whether they are movable or stationary.

What we claim is 1. In a plate glasssetting for windows, a frame to receive the plate glass, a nonresilient molding substantially U-shaped in cross-section having one narrower and one broader flange, said narrower flange directly engaging said frame with a plane surface,

fixing screws screwed from that side of the window which faces the room, through said, surface to secure said molding detachably to said frame to form a substantially rigid construction therewith, a strip of sheet metal betweensaid glass and said frame, and resilient tongues on said strip engaging said glass to press it against said broader flange.

2. In a plate glass setting for windows, a frame to receive the plate glass, non-resilient moldings having surfaces directly engaging said frame, fixing screws, screwed from the inner side of said window through said surfaces to secure said moldings detachably to said frame to form a substantially rigid construction therewith, strips of sheet metal between said glasses and said frame, and resilient tongues on said strips engaging said glasses to press them apart against said moldings.

3. In a plate glass setting for windows, a frame to receive the plate glass, a non-resilient molding substantially U-shaped in cross-section having one narrower and one broader flange, said narrower flange directly engaging said frame with a plane surface, a further non-resilient molding substantially Z-shaped in cross section directly engaging, said frame with a plane surface on one of its flanges, fixing screws screwed from the inner side of said window through said plane surfaces to secure said moldings detachably to said frame to form a substantially rigid construction therewith, strips of sheet metal between said glasses and said frame, and re silient tongues on said strips engaging said glasses to press them apart against said mouldings.

In testimony whereof we have signed our names.
